Weather in September
Temperature
Upon the beginning of September, Chattahoochee's high-temperatures register at a still tropical 87.3°F (30.7°C), closely mirroring the preceding month. Chattahoochee reports an average nighttime low-temperature of 69.6°F (20.9°C) in September.Heat index
Throughout September, the heat index is evaluated at a very hot 102.2°F (39°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
